Bone cements and other bone filling materials are currently used throughout the skeletal system to augment or replace bone weakened or lost to disease or injury. One example of a treatment that includes the administration of bone filling material is vertebroplasty. During vertebroplasty, the cancellous bone of a vertebral body is supplemented with bone filling material. Frequently, the available bone filling materials do not possess material properties similar to the native bone. Materials, systems, and methods are needed to form and deliver bone filling materials that may be selectively matched to the natural bone undergoing treatment.
